LOCKING DEVICE FOR HAT-FASTENERS.

SPECIFICATION forming part of Letters Patent No. 767,108, dated August9, 1904:.

Application filed March 4, 1904- Serial No. 196,582. (No model.)

To (all whmn, it petty concern:

Be it known that I, J AMns R. GALLAGHER, a citizen of the United States,and a resident of Buena Vista, in the county of Hudson and State of NewJersey, have invented certain new and useful Improvements in Means forLooking the Pins of Hat-Fasteners, of which the following is aspecification.

My invention relates to improvements in means for locking the pin of ahat-fastener; and the object of my invention is to provide meansforlocking in position pins or bolts by means of a frictional clutch.

This device is adapted for varied uses, but is especially designed forsecuring the pin of a hat-fastener in position after the same has beenpassed through the body of the hat and to prevent the pin from workingloose. I attain this object by the mechanism illustrated in theaccompanying drawings, in which- Figure l is a sectional View of mydevice complete. Fig. 2 is a view of the socket member. Fig. 3 is a viewof the retainingnut. Fig. 4 is a view of the clutch-nut.

Similar letters refer to similar parts throughout the several views.

A socket member a, slightly concave on its outer face at, having aprojecting section 6 longitudinally perforated and split at its outerend 6 and provided with exterior screwthreads CZ intermediate of thesplit end and the base, is formed upon the opposite side of the socketmember. The outer split end of the projecting section 2 is smooth andtapered to enter the clutch nut 0. An interiorlyscrew-threaded nut Z) isprovided to fit upon the thread d. A clutch-nut c, with a longitudinalperforation 0', provided with interior screw-threads, having the openingat one side larger than the opening at the other side, is provided tofit upon the projecting section 6. The outer end of the longitudinalperforation of the projecting section a being smaller than the innerend, the split end e of the projecting section 0 of the socket member awill be closed by screwing the nut 0 upon the split end a of the socketmember. I also provide small points or lugs a a upon the inner face ofthe socket member a beneath the screw-nut 7) to hold the devlceinposition.

The action of my device is as follows: The socket member a is insertedin the article to which it is desired to attach the pin. The screw-nut tis then fitted over the projecting end 6 of the socket member (1/ and isscrewed down upon the threads (Z until the socket member a is securelyattached. A pin or bolt is then inserted in the longitudinal perforationa in the socket member a to the point where it is desired to lock it,and the clutchnut c is placed over the projecting end 0 of the socketmember a and screwed upon the thread at until the split end 0' of thesocket member a securely grips the pin 11, when it will be found thatthe pin will be securely locked against withdrawal. When it is desiredto release the pin 2, a turn of the nut 0 will permitthe spring actionof the end a of the socket member 0 to open,'and thus release the pinThe parts need not then be taken apart or separated, but may remain inposi tion, and whenever it is desired to lock the pin p it may beinserted as before and gripped by the screw action of the nut c.

Having thus described my invention, what I claim is- A device of thecharacter described comprising a socket member provided with aslightly-concave base, an integral, hollow section having externalscrew-threads formed on the base, a plain, reduced split end portionforming a tapering projection on said section, a securing-nut carried onthe screw-threaded portion of the section, and a nut provided with anenlarged opening having screw-threads therein adapted to receive thethreaded portion of the hollow section, and having a re duced taperedopening within which seats the tapered end portion of the said section,substantially as set forth.

Signed at New York city, in the county of New York and State of NewYork, this 18th day of February, A. D. 190&.

JAMES R. GALLAGHER.
